As a result new explicit formulas for the KdV hierarchy are obtained. Our method is based on an asymptotic expansion of resolvent kernels of elliptic operators due to S.Agmon and Y.Kannai.7 pages, AMS-LaTeXExactly Solvable and Integrable SystemsMathematical PhysicsFrom Agmon-Kannai expansion to Korteweg-de Vries hierarchytext
